Six high-speed steel twist bits comprise the INGCO AKDB1065 set for boring through metal, wood, and plastic. Under the DIN 338 standard, these HSS twist drill bits maintain structural integrity during high-torque applications. A gold oxide coating manages heat buildup during rapid rotation in metalwork.
Key Features
- 118-Degree Split Point: Self-centering tip prevents bit wandering on smooth metal surfaces. Starts holes accurately without requiring a center punch.
- HSS Construction: High-speed steel alloyed with chrome and vanadium resists heat deformation. Bits stay sharp during long drilling sessions in high humidity.
- Material Rating: Hardened bits cut through alloyed steel, cast iron, and plastics. Handles diverse repair tasks without immediate bit failure.
- Gold Oxide Coating: Friction-reducing surface treatment improves chip evacuation from the hole. Stops the bit from binding or overheating in deep bores.
- DIN 338 Standard: Precision manufacturing creates consistent shank diameter and flute length. Fits securely into standard 10mm or 13mm drill chucks.
Frequently Asked Questions
Can INGCO HSS bits drill through stainless steel?
These bits penetrate alloyed steel and cast iron but overheat on hardened stainless steel. High-speed steel lacks the cobalt concentration required to maintain hardness against stainless surfaces.
